4^5
Note that the given number is same as 66000.0. Move 4 decimal places to the left, so the exponent for base 10 is 4. Hence, in scientific notation, the number is .. 6.6 x 104
The exponent is 4, the base is 18. (184 = 104,976).
43 = 4 * 4 * 4 = 64.
4 x 101
2.2237 x 10^4
5 x 10^4
6.213*105
10 with an exponent of -6 = 4
You evaluate the powers of 10 and a exponent of positive 4.
The mantissa is multiplied by 10 raised to the power as shown by the exponent. So, if the exponent is 4, then you multiply the mantissa by 10^4 = 10,000. If the exponent is -4 then you multiply the mantissa by 10^(-4) = 0.0001 or, equivalently, divide by 10^4.
20000 using the exponent of 4 = 11.89214fourth root of 20000 = 11.8921
For 104 the base is 10 and the exponent is 4.
4000000 = 4*106
Move 4 decimal places to the right to obtain the exponent of base 10 -4. Therefore, 0.00069 in scientific notation is 6.9 x 10-4
The exponent tells you how many times the base is used as a factor. 10^4 = 10 x 10 x 10 x 10
